Abstract: 218,141. Johnson, E. Aug. 13, 1923. Auxiliary actuating gear; cam and lever actuated pumps; stroke, varying.- In a pump 34 for delivering variable, charges of fuel to the injection nozzle of an internal - combustion engine, the pump plunger 35 is actuated on its pressure stroke by a lever 37 and cam 40. and on its suction stroke by a spring 36. The length of the suction stroke is limited by a lug 42 on the lever 37, which engages a set screw 43, mounted on a member 44 rotatable about the same axis as the lever 37. The adjustment of this member 44 is effected by a screw 46, which bears against a post 47 rigid with the engine frame, a spring 48 being provided to ensure that the screw is in contact with the post. A handle, 50 provides for the manual operation of the pump at starting.

Abstract: 1,030,928. Liquid-liquid contactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 21,1964 [May 24,1963],No. 20935/63. Heading B1F. A liquid-liquid contactor comprises a column rotatable coaxially within a contactor vessel, wherein said column is provided with a portion of reduced diameter, said portion registering with a portion of the contactor vessel of increased diameter. In a specific embodiment, Fig. 1, a batch process is operated. A solution to be extracted is added to contactor vessel 11 by inlet 20 while valves 22, 24 and 26 are closed. The solution is added up to level 27 (static interface), and then the column 12 rotated at 50-250 r.p.m. whilst a solvent of lower density is added under pressure through valve 22. The shearing action of the column 12 and the vessel 11 breaks the lighter solvent into droplets which eventually coalesce in portion 17 to form a coherent layer at the dynamic interface 28. The rotation is stopped and the liquid system allowed to settle. Once the interface has dropped back to 27 the lighter solvent is run off through 26 whilst the heavier solvent is removed through valve 24. In an alternative embodiment (Fig. 2, not shown), an apparatus suitable for continuous operation is disclosed. In this second embodiment, the enlarged cylindrical portion 17 is replaced by a sperical portion in which will be the dynamic interface. The lighter solvent is continuously withdrawn from the top of the apparatus from above the interface whilst the heavier solvent is withdrawn from the bottom of the apparatus.

A process for the electroless deposition of nickel from a solution containing an alkaline hypophosphite and a nickel salt on to a surface which catalyses the reaction comprises withdrawing liquid from the bath and returning it immediately in a rapidly moving stream after the addition of make-up quantities of reagent and base fed continuously to the stream, the stream flowing throughout the plating period or at selected periods during the operation. As shown, the vessel 1 to be plated is mounted on rollers 2 in a stove 3 heated by an oil burner, steam, or hot air. The liquid from an overflow pipe 19 is circulated by a pump 17 through a recycling pipe 20 back to the vessel, fresh reagents being added from three injectors 21. A portion of the bath may be subjected to regeneration in the conventional manner, the amount being between 10 and 100% of that treated according to the invention.

[Class 124] A multiple blade sawing machine for marble comprises a blade frame reciprocated by a connecting rod 3 articulated with a driving member 10 through an eccentric turntable with respect to the rod and about the driving member, means being provided for turning the eccentric whereby the effective length of the connecting rod is adjustable. The crank pin to which reciprocates the connecting rod 3 is supported by the self-aligning radial roller bearing 14 in the bore 9 formed eccentrically in the worm wheel 6. Rotation of the hand-wheel 13 actuates the worm 7 to turn the wheel 6 so that the angular disposition of the bore 9 and the crank pin 10 supported within it, is altered relative to the axis of the rod 3, thus changing the effective distance between the driving pin 10 and the blade frame (not shown). This adjustment can be made without stopping the machine; also the hand-wheel may be replaced by gearing arranged to effect the adjustment automatically as a result of the vertical movement of the frame during sawing.

Filed: 1936-07-31
Abstract: 484,470. Oil burners for refrigerating-apparatus &c. ELECTROLUX, Ltd. July 31, 1936, No. 21270. Convention date, Aug. 17, 1935. [Class 75 (i)] In a refrigerator cabinet fitted with oilheated refrigerating-apparatus in which the oil is caused to flow to an elevated point by a pump or air pressure produced by a pump, the pressure above the oil in the storage vessel is regulated thermostatically according to the temperature within the cabinet. In the cabinet shown in Fig. 1 a pump 6 supplies air to a pressure chamber 32 communicating through a pipe 34 with the oil vessel 11 which is connected to the burner 15 of the boiler 16 of the refrigerating-apparatus by a pipe 13. When the cabinet reaches a predetermined temperature a thermostat 20 operates a valve 33 in the pipe 34 to shut off the chamber 32 and to allow the air in the vessel to escape through a pipe 35. A second thermostatically operated valve may be provided between the valve 33 and. chamber 32 operating at a slightly higher temperature than the thermostat 20 to shut off the chamber 32 without relieving the pressure in the storage vessel 11 or the valve 33 may shut off the chamber 32 at a higher temperature than that at which it opens the pipe 35. A valve 36 is operated thermostatically on the extinction of the burner flame to shut off the oil supply and to allow the air in the vessel 11 to escape through a pipe 37. The pump 6 may be operated manually, by a connection to the cabinet door 3, or by an electric motor controlled by the movement of the door. Fig. 2 shows the burner 17, in addition to heating the boiler 50 of the refrigerating-apparatus, heating the coil 53 of a gas bubble pump supplying oil from the vessel 11 to a chamber 54 from which oil is conveyed to the burner through a pipe 56 and vapour through a pipe 55. The amount of oil pumped is regulated by a thermostat in the refrigerating cabinet controlling the air connection of the vessel 11. A thermosiphon pump may be used instead of the gas bubble pump 53. The Specification as open to inspection under Sect. 91 states that the invention is applicable to heating cabinets, warm water producers, &c. It also comprises a refrigerating heating apparatus in which a pump operated manually or by the door or other moving part of the cabinet supplies air directly to the oil storage vessel and a thermostat in the cabinet operates a valve in a flexible pipe conveying oil to the burner. This subject-matter does not appear in the Specification as accepted.
